Abstract
According to the present invention, a method for inserting scan hardware into Integrated Circuits (IC) such as microcontrollers is disclosed. Custom scripts used by electronic design automation (EDA) tools are configured to accommodate those microcontroller designs that operate with multiple clocks and legacy cores. Furthermore, according to the present invention, custom script are used to provide buffering circuits to drive the scan hardware.
